PROBLEM TO BE SOLVED: To convert each of parallel data of the X coordinate for each X coordinate detection line and parallel data of the Y coordinate for each Y coordinate detection line into serial data and output them. SOLUTION: A substrate 3 having pixel electrodes 5, TFTs 6 for display, scanning lines 14, and signal lines 15 includes: X coordinate detection lines 19 and Y coordinate detection lines 20; TFTs 6a for X coordinate detection; TFTs 6b for Y coordinate detection; output lines 21a and 21b respectively connected to drain electrodes of TFTs 6a and 6b for X coordinate detection and Y coordinate detection; TFTs 6a for X coordinate detection where the gate electrodes are connected to the scanning lines 14 and the source electrodes are connected to the X coordinate detection lines 19; TFTs 6b for Y coordinate detection where the gate electrodes are connected to the scanning lines 14 and the source electrodes are connected to the Y coordinate detection lines 20; an output line 21a connected to the drain electrodes of the TFTs 6a for X coordinate detection; and an output line 21b connected to the drain electrodes of the TFTs 6b for Y coordinate detection.
